Application filed January 1%, 1921. Serial No. 437,326.

To all to from it may 0011 cam Be it known that I, .losnrrr 11mins, acitizen of the United States of. .ilmerica, anda resident of Roxbury, inthe. county of Suffolk and State of Massachusetts, have invented certainnew and useful improvements in BotaryIBrushes, of which the following isa specification,

This invention relates toi'otarybrushes and has for its object theprovision of a device of this character which willfhave considerablerigidity, will lie-effective in operation and which 'inay be.constructed economically.

The invention consists primarily of brush made up of various sectionsmounted upon a tubular member secured at its ends to a revoluble' shaft.

The invention further consists of novel means for clamping the brushsections end to end andlockingthem in clamped position.

The invention further consists in certain novel features of constructionand arrangement of parts which will be understood readily by referenceto the description of the drawings and to the claims to be hercinaftergiven.

For the purpose of illustrating theinvention, one preferred form thereofis illustrated in the drawings, this form having been found to givesatisfactory and reliable results although it is to be understood thatthe "arious instrumentalities of which the invention consists can bevariously arranged and organized and the invention is not limited to theprecise arrangement and organization of these instrumentaltities asherein shown and described except as required by the scope of theappended claims.

Of the drawings:

Figure 1 represents a longitudinal section of a brush embodying theprinciples of the present invention.

Figure 2 represents an end elevation of the same.

Figure 3 represents a transverse section of the end brush-supportingmembers, and

Figure 4 represents an elevation of a portion of the outer perforatedtube of the brush.

Similar characters indicate like parts throughout the several. figuresof the drawings.

in the drawings, 10 is a tubular member provided with helical threads 11at the opposite ends thereof- Superimposed upon the tubular member 10are a plurality of rings 12- prefcrably of wood or some similar cheapmaterial.

These rings 12 are provided with cylindrical hubs 13, laof differentdiameters the smallerhub extending-beyond the outer face'of the largerhub 14.

The hubs. lt extend into the oppositeends of tubes 15andsupport the sameparallel Wit-l1. the axls of, the tuluilarinember 10 and contentricthereto. i

In asimilar manner the cylindrical hubs before being used are subjectedto a bath in a waterproof material. 1

The spaces between the tubes 15, 16 are.

filled with cement 17 and embedded .in this cement 1.7 are the innerends 18 of a plurality ofibristles 19 extending throughthe smallperforations 2-0 formed in the outer tube 1.6. 1 i.

The end Tings 12 haveisecured to the outer faces thereof the collars21:by means of screws 22 extending through said collars into the endrings 12*.

These collars 21 are mounted upon the threaded ends 11 of the tubularmember 10 and are adjustable endwise thereof to clamp together thevarious sections of brushes and supporting rings 12, 12

Secured to each collar 21 by means of bolts 23 is an annular member 524ihaving a bearing 25 for the revoluble shaft 26.

This shaft 26 is provided with a key 27 extending longitudinally thereofand adapted to coact with a keyway 28 in the annular member 24c therebyproviding a means for causing the brush to positively rotate when theshaft 26 is revolved.

Toprevent end movement of the brush on the shaft 26 each annular member24 is provided with a set screw 29, the inner end of which is adapted toimpinge upon the key 27 and lock the brush in position.

Each collar 21 is provided with a cylindrical hub 30 which extends intoa cylindrical recess in the inner face of the annular member 24 toinsure concentric relation of these members 21 and 2-1 when the variousparts of the device are assembled. V

This makesa very simple construction of rotary brushes adapted for manyuses.

By making the brush in various sections separated by the rings 12, anynumber of" "sections may be locked together upon the tubular member 10making abrush of any desired length all of the elements being usedwith-the exception of the tubular member 10, of which a diiferent oneofthe required length must be provided in each case;

It is believed that the operation and many advantages of the inventionwill be understood Without further description.

Having thus described my invention, I claim- I V 1. The combination of atubular member having threaded ends; collars threaded to said ends; abrush on said tubular member between said collars and secured thereto;an

' annular member secured tothe outer face of each collar; and arevolubleshaft in said' annular members and keyed thereto. 2. The combination ofa tubular member dhaving threaded ends; collars threaded to said ends; aplurality of rings slidably mounted on said tubular member; cylindricalmembers between said rings and supported. thereby; bristles secured insaid cylindrical members; means for locking said collars to the endrings; and a revoluble shaft to rotate said collars.

3. The combination of a tubular member having-threaded'ends; collarsthreaded to said ends; a plurality of rings slidably mounted on saidtubular member; cylindrical members between said rings andsupportedthereby; said cylindrical members each being composed of two separatedtubes with cement filling the space between them; bristles secured insaid cylindrical members; means for locking said collars to the endrings; and a revoluble shaft to rotate said collars. I

4. The combination of a tubular member having threaded ends; collarsthreaded to said ends; a plurality of rings slidably mounted on saidtubular member and hav ing cylindrical hubs of different diameters thesmaller of said hubs extending beyond the outer face of the larger hub;two tubes interposed between said rings with their ends supported bysaid hubs and the space between said tubes filled with cement; brislars;an annular member fitted over the cylindrical hub of each collar; boltsextending through said annular members into said collars; and a.revoluble shaft to which said annular members are secured.
